Stormwater Site Plan Submittal Te 1111 ,• � �
Project Overview 0���V, '
�Q�o
1. Describe the proposed developed conditions of the site. Indicate po ityi and
relative size of proposed improvements on the site map.
In the developed condition, a 2600 s.f. single family residence and 845 s.f
driveway will be constructed.
Existing Conditions Summary
2. Describe the existing topography. Indicate contours on the site map.
The existing topography slopes toward Hood Canal with grades of about 1-5%
up to the bluff line, from there it is steeper than 1:1 down to the ordinary high
water line of Hood Canal
3. Describe the existing vegetation. Indicate native vegetation areas on the site map.
Existing vegetation on-site consists of approximately 25%wooded, native
vegetation, and 75%lawn.
4. Describe the existing soils. Indicate soil type on the site map.
According to the Geotechnical report completed in May of 2009 by Zenovic&
Associates, Inc. existing soils on-site are consistent with Alderwood soil types as
shown on the SCS soil survey maps, with the exception that the surficial gravelly
sandy loam is typically deeper than is typical for Alderwood soils, extending up to
60". Alderwood soils are typically moderately well-drained, dominantly strong
sloping to steep, gravelly soils underlain by glacial till. See attached geotechnical
report for further information.
5. Describe the existing site hydrology (i.e., drainage; behavior of water on the
site—above, below, and on the ground). Indicate existing stormwater drainage to
and from the site on the site map. Depict separate drainage basins on the site map,
if applicable, and indicate acreage of each.
All stormwater runoff on-site sheet flows over the existin. bluff lain n`1
Hood Canal '; 11.741_ _it
6. Describe any excess levels of noise generated by the propo d ": X alter 2012
sem
r r
The re-development is not anticipated to cause any excess noise. The property
will maintain a rural residential state.
7. Describe significant geographic features and critical areas (i.e.,environmentally
sensitive areas such as wetlands,streams, steep slopes, etc.) on the site. Indicate
location on the site map.
The site lies on the shores of Hood Canal, which contains tidal wetlands up to
the mean high or higher water mark. Aside from the tidal wetlands mentioned
above,there is a steep bluff along the eastern portion of the property.
8. Describe the general vicinity of the site,including adjacent land uses and
structures, utilities, roads, and sensitive/critical areas (streams,wetlands,lakes,
steep slopes,etc.).
The site lies in a rural residential area and is surrounded by existing homes on
parcels of similar size. Aside from the tidal wetlands mentioned above, there is a
steep bluff along the eastern portion of the property.
Permanent Stormwater Control Plan
This portion of the Stormwater Site Plan consists of the selection and installation of
the appropriate stormwater control BMPs and facilities to remain in place after
construction of the project is completed.
"Medium" size projects are required to have the totals calculated of all impervious
surfaces,pollution-generating impervious surfaces, and pollution-generating
pervious surfaces to verify that the thresholds for treatment facilities and flow
control facilities are not exceeded.
9. Describe the developed site hydrology, as proposed. Indicate whether
stormwater will be fully dispersed(i.e.,per BMP T5.30 in the Manual) or,if not,
what types of stormwater flow control will be utilized for the site or specific
threshold discharge areas within the site. Locate these facilities on the site plan and
differentiate proposed facilities from existing facilities.
All of the roof runoff will be tight-lined into an infiltration trench,which is sized
to handle 100%of the site runoff according to the Western Washington
Hydrology Model (WWHM). Runoff from the driveway will not be controlled.
Because the site is a medium project, it is only required to comply with minimum
requirements 1-5 of the Stormwater Management Manual for Western
Washington(SWMMWW). The site is in a coastal SIPZ which requires
infiltration.
10. If the project requires the use of stormwater treatment facilities,describe the
types of stormwater treatment facilities proposed for use on the site. Locate these
facilities on the site plan and differentiate proposed facilities from existing facilities.
[This is normally for"large"projects or projects that involve the potential for
dispersion of contaminants.]
This is "medium"project and is not required to provide runoff treatment.
11. Describe the performance goals and standards applicable to the project.
This project intends to fulfill the "medium"project requirements, which include
minimum requirements 1-5 of the SWMMWW.
12. Describe the flow control system.
All runoff from the proposed residence will tight lined to an infiltration trench.
Flow control is not required because the project is considered a "medium"
project.
13. Describe the water quality system.
The site is not required to provide water quality treatment because it is a
"medium" project, and the small additional PGIS does not exceed the threshold
for runoff treatment.
14. Describe the conveyance system analysis and design.
There are no conveyance systems present on-site.
15. Describe the source of fill material,physical characteristics of fill material, and
deposition of excess material.
Fill material has not yet been sourced,but must meet requirements of Section 9-
03.10 of the WSDOT Standard Specifications, current edition.
16. Proposed methods of placement and compaction consistent with the applicable
standards on Appendix Chapter 33 of the Uniform Building Code.
The foundation material underneath all structures shall be moisture conditioned to
within 3 percent of optimum moisture content and shall be placed in loose,
horizontal layers. The thickness of layers shall not exceed 8" for compaction by
heavy equipment and 4"for compaction by hand-operated mechanical
compactors.
Layers shall be compacted to a dense state equaling at least 95%of the maximum
dry density,using the modified proctor, per ASTM D1557. Prior to the placement
of fill below structures, any and all groundwater and surface water shall be
drained or pumped from areas to be filled.
17. Describe the proposed surfacing material.
Top rock layer shall be crushed surfacing top course that substantially conforms
to Section 9-03.9(3)of the WSDOT Standard Specifications,top course
gradation.
18. Describe methods for restoration of the site.
Site disturbance is expected to be limited to the building area. The septic system
has already been installed. Any topsoil that is removed during excavation shall be
stockpiled on-site and re-used during restoration. Any soil disturbed during site
development shall be restored per BMP T5.13 (see attached).
19. An Operation and Maintenance Manual is required for each flow control and
treatment facility. [This is normally required for"large"projects only and only
those for which facilities are required to control flow or treat runoff.] If included,
list the Manuals here.
N/A
20. List here and include any special reports or studies conducted to prepare the
Stormwater Site Plan.
N/A
21. List other necessary permits and approvals as required by other regulatory
agencies. If those permits or approvals include conditions that affect the drainage
plan or contain more restrictive drainage-related requirements, describe those
conditions or restrictions here.

CONSTRUCTION STORMWATER POLLUTION PREVENTION
PLAN (SWPPP)
The Construction SWPPP addresses sediment and erosion control during construction.
The BMPs indicated by the applicant in the template that follows must be installed on the
ground during all construction phases of the project. The proponent is responsible for
preventing sediment and erosion impacts to environmentally sensitive areas and of site
areas. Consult the Construction Stormwater Pollution Prevention(SWPPP)Best
Management Practices (BMPs)Packet for guidance, particularly with rural residential
development.
SECTION I—CONSTRUCTION SWPPP NARRATIVE
1. Construction Stormwater Pollution Plan Elements. Describe how each of the
Construction SWPPP elements has been or will be addressed. Identify the type and
location of BMPs used to satisfy the required element. If an element is not applicable
to the proposal,justify in writing. Descriptions of the 12 Elements are found at section
2.5.2 of the Manual (beginning on page 2-15).
12 Required Elements—Construction SWPPP
1. Mark Clearing Limits.
Clearing limits will be establish prior to any site work taking place.
2. Establish Construction Access.
A construction entrance will be installed per BMP C107 and is noted on the site
plan.
3. Control Flow Rates.
Soil disturbance shall be limited to the building pad. Any runoff leaving the site
shall have to pass through existing vegetation and silt fence,providing flow
control benefits.
4. Install Sediment Controls.
Silt fence will be installed just east of the building site to prevent sediment from
leaving the site. See site plan for details.
5. Stabilize Soils.
All disturbed soils shall be restored per BMP T5.13 and stabilized per BMP
C120.
6. Protect Slopes.
There are no steep slopes on-site, other than the existing bluff which will not be
disturbed.
7. Protect Drain Inlets.
There are no drain inlets present on-site.
8. Stabilize Channels and Outlets.
No Channels will be constructed on-site.
9. Control Pollutants.
There are no pollutants anticipated to be present on-site.No fueling of heavy
equipment and vehicles will be allowed.
10.Control De-Watering(the act of pumping groundwater or stormwater away
from an active construction site).
No groundwater is anticipated to be encountered during the project,however, if
groundwater is encountered,the dewatering of soils known to be free of
contamination will trigger BMPs to trap sediment and reduce turbidity. At a
minimum, geotextile fabric socks/bags/cells will be used to filter this material.
Other BMPs to be used for sediment trapping and turbidity reduction include the
following:
Concrete Handling(BMP C151)
Use of a sedimentation bag, with outfall to a ditch or swale for small volumes of
localized dewatering.
11.Maintain Best Management Practices (BMPs).
All temporary and permanent erosion and sediment control BMPs shall be
maintained and repaired as needed to assure continued performance of their
intended function. Maintenance and repair shall be conducted in accordance with
each particular BMPs specifications
12.Manage the Project.
From October 1 through April 30, clearing, grading, and other soil
disturbing activities shall only be permitted if shown to the satisfaction of
the local permitting authority that silt-laden runoff will be prevented from
leaving the site.
All BMPs shall be inspected,maintained, and repaired as needed to assure
continued performance of their intended function. Site inspections shall
be conducted by a person who is knowledgeable in the principles and
practices of erosion and sediment control

DETERMINING STORMWATER MANAGEMENT REQUIREMENTS:This stormwater calculation worksheet should be completed first
to classify the proposal as"small: medium,'or large." The size determines whether a Stormwater Site Plan is required in conjunction
with a stand-alone stomRwater management permit application, building permit application,or other land use approval application that
involves stonnwater review. The basic information will also be helpful for completing a Stormwater Site Plan,if required.

activity is any activity that results in movement of earth,or a change in the existing soil cover(both vegetative and
non-vegetative)and/or the e6i isfing sod topography. Laid disturbing activities include, but are not limited to dealing, grading, filing,
excavation.and compaction associated with stabilization of structures and road construction.
Native a vegetation is vegetation comprised on plant species,other than noxious weeds,that are indigenous to the coastal region of the
Pacific Northwest and which reasonably could have been expected to naturally occur on the site. Examples include species such as
Douglas fir.western hemlock,western red cedar,alder,big-leaf maple,and vine maple;shrubs such as willow,elderberry,saimonberry,
and salal;herbaceous plants such as sword fern,foam flower.and fireweed.

Impervious surface is a hard surface that either prevents or retards the entry of water into the soil mantle as under natural conditions
prior to development. A hard surface area which causes water to run off the surface in greater quantities or at an increased rate of flow
from the lbw present under natural conditions prior to development. Common impervious surfaces include, but are not limited to roof
tops,walkways, patios,driveways, parking lots or storage areas,concrete or asphalt paving, gravel roads, packed earthen materials,
and oiled,macadam or other surfaces which similarly impede the natural infiltration of stormwater.

FURTHER INSTRUCTIONS: If the answer is yes, the proposal is considered redevelopment and the attached Figure 2 should be
used to determine the applicable Minimum Requirements. If the answer is no,the proposal is considered new development and the
attached Figure 1 should be used. At this juncture,the applicant should refer to the applicable Flow Chart to determine the Minimum
Requirements for stormwater management. DCD staff will help verify the classification of the project and the application requirements.
For proponents of "small" projects who must comply only with Minimum Requirement #2—Construction Stormwater Pollution
Prevention--an additional submittal is not required. The proponent is responsible for employing the 12 Elements to control erosion and
prevent sediment and other pollutants from leaving the site during the construction phase of the project. Pick up the Construction
Stonnwater Pollution Prevention(SWPP)Best Management Practices(BMPs) Packet Proponents of"medium"projects--those
that must meet only Minimum Requirements #1 through #5—and for 'large" projects—those that must meet all 10 Minimum
Requirements—are required to submit a Stonnwater Site Plan. DCD has prepared a submittal template of a Stomhrvater Site Plan,
principally for rural residential projects. Complete the template in the Stormwater Site Plan instructions and Submittal Template or
prepare a Stormwater Site Plan using the step-by-step guidance in the Stonnwater Management Manual.

Re: Property on East Fir Street, Port Ludlow
Par. No. 821-233-001
Dear Mr. and Mrs. Gruber:
Zenovic&Associates, Inc. presents herein the results of our geotechnical review of the
referenced property, located on the west side of Hood Canal, east of Port Ludlow,
Jefferson County. The property is situated along the shoreline of Hood Canal at the east
end of East Fir Street. Access to the site is from East Fir Street, off of Paradise Bay
Road, approximately two miles north of Highway 104 at the west end of the Hood Canal
Bridge.
We understand that your intent is to construct a single-family residence on the subject
property. A portion of the site is mapped as an Unstable—Recent Slide slope on the
Jefferson County Shoreline Map. Slopes designated as recent slides are based on
evaluations completed in the 1970s. Subsequent sliding has not been documented by
the State and is subject to our review and conclusions.
PURPOSE AND SCOPE OF SERVICES
The purpose of the geotechnical review is to provide information regarding the soil and
slope stability in order to develop the site in a manner that will not induce soil erosion or
endanger on-site or adjacent off-site properties, consistent with the requirements of the
Jefferson County Unified Development Code (JCC Chapter 18.22). The scope of the
review included a field inspection of the site and determination of site and adjacent
property slopes using a hand-held clinometer. No topographic mapping services have
been provided by this office.
Research of available data included a review of aerial photos as provided on the
Jefferson County website(1994, 2000, 2006), the Soil Survey of Jefferson County Area,
Washington (USDA/SCS, August, 1975), the Washington State Coastal Zone Atlas, ano
Jefferson County Unified Development Code.

REGIONAL GEOLOGIC AND SOIL CONDTIONS
According to the Soil Survey of Jefferson County Area, General Soil Map, a significant
area comprised of the Alderwood-Sinclair soil association extends south and east from
Discovery Bay to the Admiralty Inlet/Hood Canal shoreline, encompassing the majority of
the easterly portion of Jefferson County, including the Dabob and Coyle peninsulas. The
subject site is located in the easterly portion of the mapped soil association. The
Alderwood-Sinclair soils are typically moderately well-drained, dominantly strongly
sloping to steep, gravelly soils underlain by glacial till. Inspection of the soil maps of the
site indicate that the property lies within an area of Alderwood gravelly sandy loam, 0 to
15 percent slopes, that extends throughout the developed area along Paradise Bay
Road.
The Alderwood soils are derived from weathered glacial till. These soils were deposited
by the ice sheet during the Vashon stade glaciation. The Vashon Glacial Till consists of
a poorly sorted mixture of rock fragments deposited directly by the Vashon-age ice
sheet. Finer portions of the soil consist of clay, silt, and sand. These fine particles
comprise a moderately to highly compact matrix in which the coarser components
(gravel, cobbles, and boulders)are firmly imbedded.
SITE OBSERVATIONS
An engineer from Zenovic&Associates, Inc. conducted a site visit on April 21, 2009 to
observe the site slopes, vegetation, surface and immediate subsurface hydrology, and
evaluate in-situ soils for density.
Existing Slopes
The property has a gently sloping upland area, with a gradient of approximately 2 to 3
percent downhill from west to east, terminating at a near vertical marine bluff of
approximately 50 feet in height. The toe of the bluff is situated on the shoreline of Hood
Canal. The bluff has a relatively consistent slope with a gradient of in excess of 150%.
The upper portion of the bluff is a near vertical formation while the lower portion is less
steep. The material creating the less steep slope at the base of he bluff is the colluvial
material that has eroded from the bluff face due to wind erosion and the natural freeze-
thaw cycle that loosens the bluff soils.
Soil Conditions
Visual observation of the site indicates that the site soils appear to be consistently
Alderwood soil types as shown on the Soil Survey maps. Inspection of the bluff face
indicates that the depth of the surficial gravelly sand loam is typically deeper than is
typical for the Alderwood soils, extending to depths of up to 60 inches. These more
gravelly soils are less stable than the underlying compact glacial till, so some sloughing
of the upper area of the bluff face is anticipated.

Vegetation
Site vegetation consists of well maintained lawn throughout the majority of the site. A
small area of the native coniferous forest with a dense understory of brush covers the
westerly third of the property. Two large fir trees(48" diameter) are located
approximately 20 feet from the top of the bluff.
Hydrology and Drainage
The upland area of the site is basically flat as is the tributary area to the west. No
drainageways were observed on the upland area of the property or on the face of the
bank.
International Building Code Site and Soil Categorization
Seismic design parameters for this site include a seismic zone soil profile of Type D in
accordance with Table 1615.1.1 of the International Building Code.
The native surficial site soils can be classified as a sand, silty sand, clayey sand, silty
gravel, and clayey gravel consistent with Class 4 materials as set forth in Table 1804.2
of the International Building Code. Increases for depth and width as set forth in the table
footnotes are not recommended for structures within 75 feet of the top of the bank.
CONCLUSIONS
The bank is shown to be unstable—recent slides in the Washington Coastal Zone Atlas.
This determination is based on review of available aerial photography in the 1970's and
does not reflect the current situation. However, the face of the bluff does show some
minor weakness, so a setback for development is appropriate. The standard bluff
setback of one foot for each foot of height is reasonable to provide adequate protection
of any structures. This setback will be approximately 50 feet for the site; decks and
similar appurtenances may extend into the setback area consistent with Section
18.25.410(j) of the Uniform Development Code.
RECOMMENDATIONS
General
The proposed project shall be constructed in conformance with all requirements of
Jefferson County, including, but not limited to, the International Building Code and
applicable clearing, grading, drainage, and erosion control requirements.

Excavation and Grading
Excavation for the proposed foundation components of any structures on the site shall
be carried to firm, substantial, unyielding subsoil, at a depth of not less than 12 inches
feet below the existing surface grade. Excavation work shall occur not earlier than
March 1, and shall be complete to the permanent condition before October 31.
Drainage and Erosion Control
Drainage facilities shall be provided to direct the runoff from all new impervious surfaces
into a new infiltration system that is located a minimum of 75 feet from the top of the
bank. No runoff from impervious surfaces shall be permitted to flow over the edge of the
bluff.
Slope Maintenance
Proper maintenance of the existing marine bluff is critical to the continued safety of the
site and for minimizing damage to the bluff. No organic material, including grass
clippings and tree or brush trimmings should be thrown over the top of the bluff. These
materials may help hold water on the slope, thereby reducing slope stability.
On-site Sewage Disposal System
The septic tank and pump chamber for the existing on-site sewage disposal system are
located approximately 25 feet from the top of the bank. These tanks and associated
piping may remain in place. The area around these two tanks should be inspected on a
regular basis to make sure that no leakage is occurring. Visual inspection of the lawn
area around the tanks for unusual growth will be adequate.
USE OF THIS REPORT
This report has been prepared at the request of Mr. and Mrs. Franz Gruber for the
purpose of determining the relative stability of a steep bank on the subject property.
This report is specific to this site and the information contained herein is the property of
the Grubers and may not be used without their permission.
The findings set forth in the report are based on a site inspection and review of available
data. The conclusions and recommendations derived from these findings assume that
the site conditions do not vary radically throughout the site. If future excavations and/or
construction activities discover that site conditions are significantly different than those
documented herein, Zenovic&Associates, Inc. must be contacted to verify or modify the
conclusions, as appropriate.
